A stock is like a piece of a company that you can buy and sell. Sometimes, experts called analysts give their opinions on whether a stock is a good buy or not. They use a scale from 1 to 5, with 1 being a strong buy and 5 being a strong sell. Right now, some analysts think Duke Energy, a big company that provides electricity, is a good buy. But we should not trust them completely, because they might be too positive about the stock.

Instead, we can look at another way to measure the stock's value, called the Zacks Rank. This takes into account how much money the company is expected to make in the future, and it also updates more often. Duke Energy has a Zacks Rank of 4, which means it is a sell. So, it might not be a good idea to buy Duke Energy stock right now. Read from source...
